yeh but these yogis have a history that goes back before this was ever considered overated as a gimmick. Mind over matter, or years of study that concentrates on the living flesh and the powers that be inward/outward/and beyond. withstanding what is thought of a challange outside the normal aspects of day to ay life...then again It all may be a variation of the early circus in order to gather coins along the path that help continue the journey. The other thing I think about with these sort of things...is where along the way in this guy's study did he realize that it was his eyelid(s?) as aposed to any other body part, that would serve him best?
